Summary:This toner in one embodiment of the present invention has a weight average molecular weight (Mw) determined from the molecular weight distribution according to GPC of 30000 <= Mw <= 95263, the weight fraction of insoluble gel components in THF is less than 5%, and the area occupancy of components having a molecular weight of 500-1500 in the GPC molecular weight distribution is 4-10%. Selon un mode de réalisation de l'invention, un toner présente : une masse moléculaire moyenne en poids (Mw) obtenue à partir d'une distribution de la masse moléculaire selon une chromatographie d'exclusion diffusion, telle que 30000@Mw@95263 ; un rapport massique d'un composant gel insoluble dans un THF, inférieur à 5% ; et une proportion d'occupation surfacique d'un composant de masse moléculaire de 500 à 1500, sur un plan de distribution de la masse moléculaire de ladite chromatographie d'exclusion diffusion, de 4 à 10%.
